Structural Constraints to Sustainable Supply Chain Diversification: Rare Earth Elements, Business Strategy and Resilience in the Energy Transition

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Rare earth elements (REEs) are critical inputs for low‐carbon technologies, yet their supply chains remain highly concentrated and vulnerable. Although diversification is widely promoted as a strategy to enhance supply chain resilience, its feasibility in strategic material systems remains limited.

Scalable catalyst production process for oleate hydratase whole‐cell biocatalysis

open access: yesBiotechnology Progress, EarlyView.
This study establishes a scalable lactose‐induced fed‐batch fermentation for an Escherichia coli whole‐cell biocatalyst containing an oleate hydratase. Operation at a higher growth rate markedly increased biomass yields while maintaining catalyst activity and was demonstrated at 150 L scale.

Techno‐Economic Assessment of Biomethane and Biohydrogen Production From Victorian Wheat Straw

open access: yesCarbon Energy, EarlyView.
Techno‐economic assessment of biomethane and biohydrogen production from Victorian wheat straw. Off‐grid renewable photovoltaic energy with a price down to 0.95 ¢/kWh was applied. Both approaches can make positive profits and negative carbon footprints.

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes

open access: yesChemie Ingenieur Technik, EarlyView.
A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,

Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

open access: yesChemie Ingenieur Technik, EarlyView.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...
